A straight line is also known as a supplementary angle with is equal to 180 degrees.
(this is for the first one) All you have to do is subtract the measure of the known angle from 180 degrees.
180 - 40 = 140
180 - 140 = 40
(second one) 105 plus 75 is going to equal 180 degrees. Now going the vertical way (instead of horizontal, the way the know angles are shown) :
180 - 75 = 105
180 - 105 = 75
I hope this helps. Let me know if this was correct/helpful and/or you need anymore help :)
Answer:
B - perpendicular
Step-by-step explanation:
AE is parallel to CH, and since AC is perpendicular to AE, CH and AC are perpendicular
hope this helps youu
Answer:
B = 50°
Step-by-step explanation:
Because all the angles in every triangle added together equals 180°, you would divide m∠CAB (62°) by 2, giving you 31°, then add the 99° to the 31°, and you have 130°, and just by looking at it, you can see that the ∠ABD =50°
Hope this helps :)
